What is the maximum intermediate cleat spacing allowed for a wood-cleated panelboard box?

The maximum intermediate cleat spacing allowed for a wood-cleated panelboard box is crucial for ensuring the structural integrity and safety of the packaging. Cleats are essential for maintaining the stability of the panelboard and providing the necessary support to prevent deformation or failure during handling and transport.

When choosing the maximum spacing, 24 inches is the standard because it balances the need for support with practical considerations for manufacturing and handling. Any greater spacing may compromise the strength and reliability of the box under load, while closer spacing than 24 inches could lead to over-engineering and unnecessary material costs.

This spacing is established based on industry standards that take into account the weight distribution, environmental conditions during transport, and the maximum load the box can endure without damage. Understanding these specifications is essential for anyone involved in packaging and shipping, as it ensures compliance with regulations and the protection of the goods contained within the boxes.
